'Be 1t known that I, Jonn SrUr kA, a 'citi; zen of the United States, residing at West;

Pullman, Illinois, have invented certain new:

and useful Improvements in Automobile Attachments, of which the following is a specification.

This invention relates tohattachmentsjfor motor vehicles, audit comprises an overflow pipe; arranged in the cap of a radiator slightly above the usual overflow pipe, a three-way valve arranged therein, connections whereby steam may be delivered to the intake manifold, or condensed and delivered to the cylinder for removing the carbon, the second connection being connected to a petcock which permits the delivery ofwater to the cylinder, but prevents the outflow of air or gases, thereby maintaining the compression within the cylinder, said petcock having a second valved opening whereby air upon pressure may be discharged therefrom for cleaning spark plugs and the like.

In the present invention, I have provided an attachment for motor vehicles "whereby steam from the radiator is collected and may be delivered to the intake manifold to enrich the mixture. 7 The delivery pipe is provided with abranch leading to a petcockor valve in the head of the engine cylinder, whereby the steam may be first collected in the delivery pipe andthen condensed and'delivered to the cylinder while the engine is running, for the purpose of removing carbon from the walls of the cylinder. The inlet is provided with check valves in the form 'of small balls which are adapted to prevent exhaust of gases fro nthe cylinder through the inlet.

The valve or petcock. in the head oft-he engine cylinder is further provided with means for exhausting air or other gas under pressure fromthe engine cylinder when the engine is running, for the purpose of producing a blast for cleaning spark plugs and other purposes, and this outlet is provided with an automatic check valve to prevent en'- i trance of air through the nozzle on" the in ward stroke of the piston in the engine cylinder. 1 i

'In'the accompanying drawings, I have shown one embodiment of the invention. 3 In this showing, l H V J Figure 1. is a side elevation of a conventionlal ype of engine showing the invention a 1e p igure 2 is a vertical sectional view of the Specification of Letters latcnt; Application filed June 21,

' Figure 8 is a similarview on the of Figure 5. i

Referring to'the drawings, the reference line s s numeral 1 generally designates an engine 'of the usual type providedwith an intake man ifold 2,]exhaust pipe 3, and a water cooling 7 radiator 1, 'Theseparts are of the usual construction and form no part of v the present invention except in thecombination claimed.

Referring in detail to Figure 2 of the drawings, the usual overflow pipe 5 is pro} vided wherein steam produced by vaporiza tion of the water in'the radiator is exhausted fromthe' cooling system. A second over flow pipe '6 is arranged in thehead 7 of the radiator'below the cap 8. shown, the second overflow pipe is arranged withitsuppe'r end slightly above the usual overflow-pipe A s to prevent passageof any waterlin liquid. iorminto the pipe. The spacebetwee'n the upper end of the pipe and the radiator cap 7 is sufiicientfto' insure delivery of steam thereto, when steam is formed in the radiator and prevent clogging in the end of the pipe." This pipe is curved as shown" and isfprofvided with a threaded end 9 adapted to be receivedin a coupling member 10 arranged in the wiallof the' radiator. One endlofthe coupling member is provided with af flange l1 and a packing nut 12 is positioned on the' opposite side'of the radiator," suitable packing 13' being {arranged between the flange and the radiator wall and the nut andthe radiator wall to preventfleakage. The end of the coupling is screw. threaded and is adapted to be received within the main valve casing 14. As shown, this valve is provided with a plug 15 having a pairof openings 16 and 17 arrangedatapproximately 90 y from each other. i The valve is also'provided with a central bore 18 communicating with the interiorofthe coupling 10. The plug is provided with a handle 19 on its outer end to permit manipulation of the valve. The

valve casing is provided with diametrically opposed outlets 20 and 21 connecting to branch conduits 22 and 23. The first menbranch conduits communicate with valves or petcocks 26 arranged in the head of the engine cylinders.

The detail construction of the valve 26 is shown. in Figures?) to-3 of the drawings. As shown, the valve comprises a lower section having external screw threads 27 adapted to be received in the screw thread opening in the head of the cylinder. The valve body is provided with a central bore or conduit 28. The upper portion of the valve casing 29 is provided with a reduced end 30 having screw threaded engagement with the member 26. This member is provided with a central bore 31 communicating with the bore 28. A member 32 is arranged on the member 26 and is adapted to be held in place by the upper portion of the valve casing when it is placed in position. This'member isprovide with a central opening through which the lower reduced end 30 passes. As shown, the member is provided with radial offset 33 having external screw threads adapted to. engage internal screw threads in the end of the branch conduit 25. A central opening 34 is arranged in this member. The opening through which the reduced end of the upperv portion of the valve casing extends, is slightly enlarged,'-as at 35, to permit passage of water therethrough. The passage 35 communicates with openings 36 formed in the upper portion of the valve casing and connected to an enlarged central opening 37' arranged therein. A plurality of small balls 38 are arranged over the opening-s36. The enlarged opening 37 communicates with the central bore 31 by means'of radial openings 39. The upper end of the valve comprises a member 40 having external screw threads adapted to .be received in internal screw threads in the upper portion ofthe valve casing. As shown, this member 40 is provided with a central bore 41 communicating with the bores 26 and 31. The members 29 and 40 are provided with diametrically op posed radial openings adapted to receive a plug 42 having an operating handle 43. The plug 42 is tapered and isprovided with a washer or plate 44 on the small end, held in place by a pin 45. A coil spring46 is arranged between the valve casing and the plate 44 adapted to maintain the valve in proper position. The plug is provided with radial opening 47' whereby the central bore of the valve may be placed in communlcation with the atmosphere when the valve is in a position shown in Figure 6. The end of the here is provided with a recess 48 adapted to receive a ball valve 49 to prevent passage of fluid inwardly. A perforated plate 50 is arranged in the bore 41 slightly spaced from the ball valve to maintainit in proper position. The upper end of. the member 40 is provided with an "internally threaded recess 51 adapted to receive a nozzle 52 having external threads .53 engaging the threads in the recess. r f p The operation of thisdevice is as follows:

Through the medium of the main valve 14, either of the conduits 22 and 23 maybe placed in communication with the overflow. pipe 6, or both of them may be closed. As shown, the opening 16 whereby steam is delivered to the outlet pipe22, is larger than the opening 17 which is adapted to communicate with the water pipe 23. Byproper operation of the valve plug 15 through the to pass water'therethrough to remove carbon from the walls of the entrance cylinder, the plug 15 of the valve is firstmovedfto closed position whereby communication with the two outlet pipes is interrupted. The valve is then moved to the positionto bring the opening 17 in communication with the outlet 21 to deliver water to thepipe 23. This water passes into the valve 26 through the opening 34 in the radial projection 33, thence to the enlarged passage 35, to opening 36 to the passage 37, thence throughpassage 39 to the central bore-0f the valve and is delivered to the cylinder. "The balls 38 permit passage of fluid inwardly from the pipes 25 to the cylinder, but are seated by outward pressure to prevent overflow of gases outwardly from the cylinder. This prevents the loss or disturbance of the compression in the engine cylinder. in actual operation, the valve 14 is maintained in closed position until the engine hasbeen in operation for a short length of time before either. steam or water is delivered to the engine cylinder. The valve is then forced open to deliver water to, prevent the possibility of obtaining anyv condensed steam in the fluid that is delivered to the intake mani-= fold. When the valve has been in this positionlong enough to insure the removal of all water from the overflow pipe 6, it is moved to the proper position to feed steam to the steam pipe 22. In normal operation,

the plug 42 is maintained in the position shownin Figure 5 of the drawings topre-- vent exhaust of fluid under pressureby' the nozzle 52. When-the operator of the machine desires to obtain a blast of air. or other gases for the purpose 'of cleaning spark plugs'or for any other purpose, the plug is moved to the position shown in Figure 6 of the drawings, the opening 47 therein then being in alinement with the bore 41 permits passage of fluids compressed in the engine cylinder and a blast is obtained I from the nozzle outlet which is very effectual for the purpose of cleaning spark plugs. The ball valve 4:9 is arranged in the bore 41 above the plug, for the purpose of preventing inflow of air through the nozzle 52 on'the return stroke of the engine cylinder,
